If you come from outside Thailand to Bangkok, you probably can better buy your aftermarket exhaust system in the country you come from. At the moment all aftermarket exhaust systems we're aware of in Thailand are imported, and therefore subjected to the high Thai import duty – what in simple terms makes them expensive...

We where told that some of the loccal exhaust manufacturers are thinking to include Benelli exhaust systems in the product range but until now we not seen one...

I have seen a few Benelli's with a Termignoni exhaust system, which are imported by a company called Magnum... but we not know if they have Termignoni exhausts for the Benelli 600 inline-four on stock or they needed to be ordered and have an extended delivery time....

Other manufacturers who make exhaust systems for the Benelli BN600 / TNT600 are Akrapovic, Arrow, Ixil, and a few less know aftermarket exhaust system manufacturers... But again most imported exhaust are relative expensive if you come from outside Thailand....
